Why do people troll on youtube?

if you hav music on youtube and someone is talking crap about it be happy cause the more crap people say the more people will hear about you... lol more haters you get more people will ***** about your music more people ***** more ears listen

I was so upset about the comments on my youtube video of me playing some Unearth on the guitar, that i stopped playing and recording, but thanks to your post you've now inspired me to start playing again and start recording more tracks...
